Terminations of high voltage cables with insulation of cross-linked polyethylene

摘要

The invention relates to cable technology, namely, to the terminals, intended for connection of the cable lines for high voltage overhead lines via clamping hardware. End structure a high voltage cable with XLPE includes cable preparation which contains at several sites with various insulation thickness reinforcing insulation in the form of heat shrinkable tubing, which are located between the capacitor plates while under the nearest to the insulation of crosslinked polyethylene heat shrinkable tube is applied a conducting Floor, equal in length located above it the capacitance plate. The technical result - the simplification of production technology terminations of high voltage cables insulated with crosslinked polyethylene and reliability during transients. The use of heat-shrinkable tubing as reinforcing insulation terminations allows for the first time to make installation of these couplings at the factory, namely directly on the drum (upper end of the cable) and experience together with the cable drum in the factory, which significantly reduces the risk of mistakes when installing couplings field. 1 ZP f ly-1-yl.
